Constructing Covalent Organic Polymers through Dative B─N Bonds: Synthesis, Single Crystal Structures, and Physical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Regulating the Zn Electrode/Electrolyte Interface Toward High Stability– Insights from the Resting Time Impact on Zn Electrode Performance

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a close correlation among the resting period, the cyclability of the zinc anode, and the evolution of byproduct zinc hydroxide sulfate (ZHS) is identified. Furthermore, it is shown that proper control of the interfacial ZHS can significantly enhance the cycle performance of the zinc anode by effectively inhibiting corrosion and promoting

Highly‐Entangled Hydrogel Electrolyte for Fast Charging/Discharging Properties in Aqueous Zinc Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A highly‐entangled polyacrylamide (HE‐PAM) hydrogel is designed as an aqueous electrolyte for the fast charging/discharging properties in Zn/MnO2 batteries. Such hydrogel electrolyte possessed excellent mechanical characters, stable cycling capability, and superb rate performance under high current densities. These characters can also be applied in the

Access Control Mechanisms for Semantic Web services-A Discussion on Requirements & Future Directions [PDF]

open access: yesInternational journal of emerging technologies and applications in engineering, technology and sciences (IJ-ETA-ETS)ISSN: 0974-3588 | Jan 2011 -- June 2011 | Volume 4 : Issue 1 | Pages: 338-342, 2011
Semantic Web is an open, distributed, and dynamic environment where access to resources cannot be controlled in a safe manner unless the access decision takes into account during discovery of web services. Security becomes the crucial factor for the adoption of the semantic based web services. An access control means that the users must fulfill certain
